Tax Payment - Instalment Payment CP204

For existing companies, the estimated tax payable has to be paid in equal monthly instalments beginning from the second month of the basis period for a year of assessment.

For new companies, installment payments must commence in the 6th month of the basis period for the year of assessment i.e. payable in the 6th month after the company commences operations. A company is required to pay the installment of the estimated tax by the 10th day of each month.

Application To Pay Balance of Tax by Installments

If the company has not fully paid the tax for that period, the company can apply to pay the balance of tax by installments. The company can request in writing to the Collection Unit before the last date of payment of the relevant year. However, please note that even if the request is accepted, late payment penalty will still be imposed.

Penalty Under Installment Scheme

  • If a company fails to pay the monthly installment on the tax estimate by the stipulated date, a late payment penalty of 10% will be imposed on the balance of tax installment not paid for the month.
  • If the difference between the actual tax payable and the estimated tax payable (if the revised estimate is not furnished) is more than 30 % of the actual tax payable, a 10% increase in tax will be imposed on that difference.

The formula for calculating the amount of tax to be increased is as follows:
Amount of tax to be increased = {(AT-ET) – (30% x AT)} x 10% where:
AT: actual tax payable
ET: revised estimated tax payable or estimated tax payable (if no revised estimate is furnished)

Penalty for Late Payment

If the balance of tax payable is not paid by the due date, a penalty of 10% will be imposed on the outstanding amount. If the tax payable and penalty is still outstanding within 60 days from the due date, an additional penalty of 5% will be imposed on the tax and penalty outstanding.

If the tax payable and penalty is still ouAn appeal in writing within 30 days from the statement of account can be submitted to the relevant branch (Collections Unit), if the company does not agree with the late payment penalty imposed.

A tax audit is an examination of a taxpayer’s business records and financial affairs to ascertain that the correct amount of tax are reported and paid in accordance with the tax laws and regulations.


Desk Audit

A desk audit is done at the IRB’s office where IRB will send letters to selected taxpayers, requesting for documents to support the assessment submitted. This would normally involve checking all information on income and expenses as well as various types of claims made by a taxpayer in his income tax return. This usually concerns straightforward cases or tax adjustments which can be handled via correspondences or if necessary, an interview with the taxpayer at the IRB office.

Within 2 to 3 weeks after the audit, IRB will notify the taxpayer whether additional tax payments need to be made. If IRB’s review shows overpaid taxes, a refund will be made to the taxpayer.

Field Audit

A field audit is where IRB officers will audit the taxpayers’ records at their premises. It involves the examination of the taxpayer’s business records. For a sole-proprietor or partnership, it may also involve the examination of non-business records such as personal bank statements.

IRB will serve a 14 day notice to the taxpayers to prepare the necessary documents and records. There will be at least 2 officers to conduct each audit, and their names will be given in the notice.

Sometimes, IRB may conduct field audits on tax assessments up to 3 years back. Should there be discrepancy between the records and the assessment submitted, tax assessment will be amended accordingly and the taxpayer will be notified within 3 months after the audit.


Tax investigation is conducted by surprise should there be a suspicion based on precise and definite evidence that a taxpayer is deliberately trying to avoid paying tax or has committed an act of willful evasion under the tax laws. The purpose of tax investigation varies from business to business. The tax authority’s personnel will visit to the taxpayer’s business premises, personal residences, agent or representatives premises to take possession of the required documents and books of accounts for investigation purposes. Besides that, notices may be served on taxpayers, creditors and bankers of the taxpayer to collect additional information to come up with the best judgment of the tax affairs of the taxpayer.

What if taxpayers understated or omitted

their company's income and IRB finds out?

What IRB does is to ensure the taxes reported and paid by taxpayers are correctly prepared by way of conducting tax audits. IRB’s selection process for tax audits is by way of reviewing assessment submissions for irregularities in financial ratios and among others, information provided by third party.

In cases where fraud, willful defraud or negligence is detected, IRB is empowered to revise the tax computations, taking into account tax lost beyond the 6 years of investigation even though the taxpayer may not have records for those periods. If this happens, additional assessment will be issued to recover the tax lost, coupled with penalties, which can be up to 300%. In serious cases, or for repeated offenders, the taxpayer may be prosecuted and if he is found guilty, imprisonment of up to 3 years can be imposed.

To avoid penalty, it is recommended to keep a full set of records and accounts to avoid any misunderstanding in the tax audit process.
